An outline of the classification followed in this work I have 

 recently puhlished in Ann. & Mag. Nat. Hist. xiv. 1884, p. 117. 



I have given the principal measurements of most of the species, 

 taken from the largest or most perfect specimen in the collection. 

 The " length of the head " is measured to the occipital condyle, 

 and the " length of the body " signifies the distance between the 

 latter point and the anal cleft. 



The affixes to the names of donors &c., in the third column of the 

 list of specimens, may be explained as follows : — " [P.] " signifies 

 " Presented by ;" " [C] "=" CoUected by ;" "[E.]" = " Obtained by 

 exchange." Where none of these signs are employed, the specimens 

 were purchased.
